Abstract
We propose a fiber-longitudinal monitoring method that generalizes the correlation method (CM) and least squares (LS). The proposed method balances the advantages of CM and LS, achieving both high noise robustness and power sensitivity. The results are experimentally validated using 800G signals from a DSP-ASIC.
